The evacuation of cargo lines between the terminal and the tanker is a critical stage in the loading and unloading processes of liquid bulk cargoes. During the execution of this specific procedure, risks such as overpressure and overflow of the ship’s cargo tanks may arise, which can cause significant problems and delays.
Specifically, the pressure developed in the ship’s cargo tanks during the line clearing process can cause significant deformations in them. At the same time, the overflow of tanks poses a serious risk of environmental pollution and injuries to crew members.
Therefore, the effective management of the line clearing process is essential for the safety of the ship and the protection of the environment. The method and its stages depend on the terminal’s facilities and the type of cargo, but below are some general recommendations for preventing overpressure and overflow risks:
Systematic training and briefing of the crew, careful planning in cooperation with the terminal, as well as continuous, effective communication between the ship and shore, are key factors in reducing the risk of overpressure and overflow during the loading/unloading and line clearing process.
